LIQUID-FUEL EUENACE Specification of Letters Patent Patented Jan. 7, 1919.

Application med september 21, 19177. serial N. 192,603.

ToaZZ whom t may concern: Y,

Be it known that I, DUDLEY WRIGHT, a subject of the King of England, residin]g at Bankfield, Ulverston, in the county .of ancaster, England, engineer, have invented certain new and useful Improvements in or Relatin to Liquid-Fuel Furnaces, of which the folowing is a specification. 4

This invention relates to liquid-fuel heated furnaces. l i Y One feature of my invention consists in disposing a producer chamber and furnace side by side, these being separated by a vertical wall, the discharge end ,Y tube lying in an aperture extending through said wall. I

Another characteristic consists inv ther use or employment in any suitable liquid-fuel heated furnace (but more particularly a furnace otherwise embodyingl my improvements) of a gasifying tube or receptaclek of the construction heremafter described.

Further' and additional features or characteristics of the invention Vare described in the specification and; pointed out in the claiming clauses appended hereto.V Y

furnace according to my invention, comprising two portions or chambers arranged side by side,` which are-separated or divided bya vertical wall or partition wherein are formed an aperture or apertures, ports or passageswhich Vare preferably controlled by vmeans'of dampers or other suitable movableV closures. jWithin the front or gas producer chamberformed by said vertical wall, there is carried a gasifyng tube or receptacle, the discharge mouth whereof extends into a port .or passage provided for the purpose inpsaid wall, and within said gasifying receptacle,`

itself, or .pipe connected therewithris disposed a liquid-fuel atomizer preferably of .the rotary type, the oil fuel being supplied .thereto in any convenient .is usually the case,

manner. If, as it be desired to pre-heat the air for supporting combustion of the fuel in the furnace, an air supply pipe is carried through the producer chamber, be-

i ing preferably coiled on the floor thereof,

one end of said pipe being in communication witha fan air under pressure and the other end whereof communicates with the gasifying tube or receptacle. Y ,Y .Y

The liquid-fuel may also, if desired, be

of a gasifyingv `ulg Seme- Fig. 2 a front view or other means of transmitting A .an enlarged conveniently heated inits passage to the atomizer by conducting the supply pipe through the producer chamber.

The gasifying tube or receptacle which I prefer touse 1sV characterized in that the floorv thereof is flat, the tubey being approximately segmental shape or configuration in cross section reduced 0r contracted at its discharge mouth, and within same'may be formed or fitted' ay plurality of longitudinally arranged blades or plates; said floor maybe roughened,A serra-ted or corrugated or provided with raised ledges or Vballies so arranged that any oil which may Yfall on to the floor shall take a sinuous zig-zag course through the tube orvreceptacle.

Suitable openings or flues controlledby dampers or the like are provided in the furnace wall or walls, as required. Y

Said producerV chamber is heated (that is the gasifying tube or receptacle and air and fuel pipes are heated) by the flames or heated'gases of combustion which pass back i through said ports Myl invention maybe applied to two or l Vmore urnaces, or a double ended furnace, a `singleproducer chamber being common to bothor all. Y

I will'further describe my invention with the -aid ofthe accompanying sheets-of exfplanatory'vdrawngs which illustrate, bywa of examples only, various moldes of embodyf. VIn said drawings YFigure l is in longitudinal section. partly elevation and partly in section, and Fig. 3 is a plan of a furnace and aY producer chamberintegraltherewith. y

Fig. 4` is a partsectional'p'lan drawn to scale as compared with the preceding views, jof an atomizer and a portion ofthe gasifying receptacle, and

`5,6,"and 7 'are respectively sectional plan, transverse section, and front view, of the gasifying receptacle which I prefer to employ.

Figs. 8 and 9 are, respectively, longitudinal section and front view of a producer and furnace, the former being detachably secured to the latter.

Fig. 10 illustrates in diagrammatic plan view the application of a producer common to two furnaces.

1n severalviews like characters of reference denote like or equivalent parts wherever they occur.

Referring to the drawings, but first more particularly to Figs. 1 to 4, 1 generally designates the combined producer and furnace structure which is constructed of brick Work and divided into two portions 2 and 3 by the transverse wall 4 in which are formed the converging ports or passages 5 and 6 controlled by the slidable dampers 7 and 8: 9 represents an air fan and 10 is a pipey leading therefrom and conducted around the floor of the producer chamber 2, being (see Fig. 4) screwed to a flange plate 11 to which plate is also secured the gasifying tube 12. 13 indicates an air control valve on the pipe line 10.

Vithin said gasifying tube 12 is arranged an atomizing'receptacle 14 revolubly mounted on an internal pipe 15 which extends through the pipe line 10 and emerges from the pipe line 10 to terminate in a. funnel 16 to which oil is supplied from a suitable reservoir 17. The oil discharge pipe 18 from the reservoir preferably terminates as shown above the funnel 16 so that the rate of supply of oil to the atomizing receptacle 14 may be readily ascertained by inspection; but any other sight feeding arrangement may be adopted. On the periphery of the atomizing receptacle are vanes and air under pressure passing through the pipe line is adapted to impinge against the vanes and impart a. rotary movement to the atomizing receptacle.

Should the oil supply pipe 15 be made revoluble in the air line 10 and supported by suitable bearings and a packed joint, then a lubricant cup 19 and a tube 2O may be employed to supply a lubricant to the bearings.

21, 22, indicate openings in the furnace walls for charging purposes, which openings are respectively controlled by the counter weighted dampers 23, 24. 25, 25a indicate inspection openings in the Yproducer chamber 2 respectively controlled by dampers 26, 26a, and 27 is an inspection opening in the furnace 3 controlled by damper 28.

In the floor of the producer chamber 2 and opening 29 controlled by damper 30 is provided; through said opening a lamp may be inserted for heating the gasifying receptacle on the starting up of the furnace.

31, 32, are flues leading from the furnace 3 which flues are respectively provided with removable covers 33, 34, and 35 is a flue, provided with removable cover 36 leading from the producer chamber 2. YVhen the furnace is in action the flames from the furnace proper 3 pass through said converging wall passages 5, 6, into the producer chamber 2 thereby heating the gasifying tube or receptacle 12 and also that portion of the air pipe line 10 which lies within the producer chamber.

Referring to Figs.l 3 to 7 there is disposed within the iron or steel gasifying tube or receptacle 12 a. structure embodying a plurality of plates 37, and at the front or contracted portion 12a of said receptacle there are formed baffles or ledges 38.

The object of the provision of said longitudinal plates 37 is to provide additional heating area for the fuel passing through the gasifying receptacle and the baffles 38 cause any oil which may drop to the flat floor or base of the receptacle to take a sinuous course therethrough and so, as far as possible, insure its complete gasification prior'to leaving the receptacle.

Referring now to Figs. 8 and 9, the producer chamber is constructed of sheet iron or steel and is composed of a front portion or plate 39, a casing portion 40, and outer air or water jacket portions 41, 42. The structure is secured to the furnace proper by the aid of angle plates 43.

1n this arrangement the gasifying tube 12 is provided with a flange 12b whereby it is secured to the front plate 39, the front jacket plate 42 abutting against shoulder 45 and positioned by means of the nuts 44. The air pipe line 10 is arranged to pass' around the lower jacket portion 41.

Said producer may be lagged instead of being jacketed if desired.

Referring now to the construction shown in Fig. 10, the producer chamber 2 is common to the two furnaces, 3 3a, and the pipes 12 enter the producer chamber from opposite sides thereof.

Having now described my invent-ionJ what I claim as new and desire to secure by Letters Patent is z- 1. A liquid-fuel heated furnace embodying a producer chamber and a furnace proper arranged side by side, a vertical apertured wall separating said producer chamber and furnace proper, and a gasifying relll ceptacle approximately segmental in cross section passing through said producer chamber and the discharge end whereof lies in an aperture extending through said wall.

2. A liquid-fuel heated furnace embody ing a furnace proper and a producer chamber detachably secured thereto, a vertical apertured wall separating said producer chamber and furnace proper, a gasifying receptacle approximately segmental in cross section and the mouth whereof is contracted, a plurality of longitudinal plates provided in the interior of said receptacle, and bafHe plates on the bottom of said receptacle so that oil falling thereto is caused to take a zig-zag course through said receptacle.

3. A liquid-fuel heated furnace embodying a furnace proper and a producer chamber detachably secured thereto, a vertical apertured wall separating said producer chamber and the furnace proper, and a gasifying receptacle approximately segmental in cross section and the discharge mouth whereof is contracted in the apertured wall.

4. A liquid-fuel heated furnace embodying a furnace proper and a producer chamber detachably secured thereto, a vertical apertured wall separating said producer chamber and furnace proper, cle, the mouth whereof 1s contracted in the apertured wall, and a plurality of bae plates on the bottom of the receptacle so that oil falling thereto is caused to take a zig-zag course through said receptacle.

In testimony whereof in the presence of two witnesses.
